The V51E Butterfly Valve is a firing rate valve used to provide variable flow control of natural, liquefied petroleum (LP), and manufactured gases.
It is also applicable to controlling air flow. The V51E Valve is actuated by a firing rate motor mounted directly on the valve. The V51E is not applicable as a safety shutoff valve.
The V51E Valve provides high capacity with a relatively constant relationship between flow rate and opening plate angle. The V51E firing rate motor assembly is especially adaptable to commer-cial and industrial installations that require close control of large gas capacities
